Title: Rapid actuator for tilting or rotating windows - has mechanism for two actuating modes without the use of a changeover drive
Inventor: WAGNER KARL
IPC: E05D15/52
Filed: 1974-11-08
Abstract: The actuating mechanism for rotating and tilting windows and doors is desired for rapid operation. This arrangement can be used for determining whether the window will be tilted or rotated without the actuation of the changeover drive. The arrangement has two independent locking systems one of which is locked on tilting and the other one on rotating. The rotating panel is locked in both cases after closing. The actuating lever (2) force is transmitted to the actuating element (9) via an actuating scissor linkage pivot (3). This ensures that the upper window panel part is firmly pressed against the fixed frame. The lugs (5) engage on tilting and hold the panel firmly. When the window is rotated then the lugs slide past one another without friction. The sliding bracket is pushed to pivot (3).

Title: Dryer and preheater for coal before coking - employs heat from gas used to quench incandescent coke
Inventor: POERSCH WERNER DIPL ING
IPC: C10B39/02
Filed: 1974-11-11
Abstract: A plant for drying and preheating coal before it goes to a coking furnace uses heat from the incandescent coke. A stream of gas is used to quench the coke and heat is transferred from this stream to a second stream of gas which is used to dry and preheat the coal. The drying gas can circulate around a closed path incorporating equipment to condense water vapour liberated during drying and including one side of a heat exchanger, the other side of which is a part of the circuit of quenching gas. Alternatively, the paths of both gases can be combined in a single circuit which includes equipment for condensing water vapour and in which the gas stream passes by a subsequent combustion chamber. The condensing equipment is an ejector condenser system. There is provision for injecting inert gas from a reserve receiver and a burner which can supply hot gas in place of or in addn. to quench gas. The plant does not incur difficulties which existing plants have because they use nitrogen or because their operation incurs risk of explosion from the formation of water gas or of corrosion through condensation. It uses less energy and costs less.

Title: Burner compound control - heated solid state electrolytic oxygen detector emits corrective signals to fuel-air ratio mixing assembly
Inventor: DENZER ALWIN
IPC: F23N5/24
Filed: 1975-03-12
Abstract: The present arrangement is to be used for electro-mechanically, or purely electronically controlled burner installations burning gas, oil, or coal powder with pre-programmed fuel/air ratios in relation to various load conditions. The sampling an subsequent continuous analysing of flue gases and then emitting signals for corrective action suffers from considerable sluggishness. The present design eliminates this by using a solid state electrolytic oxygen detector (4) fitted in the flue (3) which is constantly kept at a controlled operation temperature, which emits electric signals if the flue gas composition deviates from the optimum value and this signal actuates the fuel/air ration control arrangement.

Title: Air jet for cleaning bottom of drilled hole - is directed partly into hole and partly on to metal beside it
Inventor: DUEHLMEIER RUDOLF
IPC: B08B5/02
Filed: 1975-11-06
Abstract: The pipe (4) which conveys the air jet is positioned a short distance above the surface of the metal, and slightly overlapping the boring (2) to be cleaned. Thus a part only of the air enters the boring and disturbs any particles of dust or metal there may be at the bottom. The remainder of the air strikes the metal surface and is deflected outwards, creating a local vacuum. When a brief puff of air is delivered by the pipe, the combination of the two effects lifts the particles from the boring and draws them away from it, leaving it clean.

Patent DE-2610263-A1 (DE)
Title: Anti:corrosion vessel coating - consists of at least two thin layer of different conductivities for heat application and electrode energisation
IPC: H05B3/00
Filed: 1976-03-11
Abstract: The lower conductivity (heating) layer is in contact with a higher conductivity (electrode) layers are not in contact with each other. When voltage is applied to the electrodes, a current flows transversally through the heating layer, so that a uniform heating power per unit area is dissipated. The heating layer thickness is calculated from minimum distances between the mutually opposed electrode layers which penetrate into the heating layer, and from maximum voltage taken as the breakdown voltage. Resistivity is derived from the above considerations, so that the required power per unit area can be dissipated.
